Thunderstorm Wind in Webster Parish, Louisiana

Multiple trees and power lines were downed north of Shongaloo.

A weak cold front slowly advanced southeast into portions of Northeast Texas, Southeast Oklahoma, into Western Arkansas and Southern Missouri on April 30th, and focused a warm, very moist, and unstable air mass in place across much of East Texas, North Louisiana, and Southwest Arkansas during the afternoon through the evening hours. Meanwhile, an upper low pressure area ejected northeast from the Desert Southwest into the Texas Panhandle, with deep southwest flow aloft yielding weak disturbances along the front to induce large scale forcing across much of East Texas and Southwest Arkansas. As a result, a complex of strong to severe thunderstorms developed and spread into areas along and to the southeast of the front, yielding isolated instances of damaging winds across portions of extreme Northwest Louisiana during the afternoon. While these storms weakened by early evening, additional thunderstorm redevelopment occurred during the evening into a portion of the overnight hours on May 1st along the slow moving front, resulting in locally heavy rainfall and areas of flash flooding in the Shreveport/Bossier City areas.
